JOHN M. STOKOE, OF CLEVELAND, OHIO.

WlCK-RAISER FOR OlL-BURNERS.

SPECIFICATION forming part of Letters Patent NO. 7 7 9,055, dated January 3, 1905.

Application filed April 15, 1904:. Serial No. 203.292.

To all whom it may concern.-

Be it known that 1, JOHN M. SToKoE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in ick-Raisers for Oil-Burners, which improvement is fully set forth in the following specification and shown in the accompanying drawings. I

This invention relates to certain new and useful improvements in wick-raisers for burners for oil-stoves and the like, and it pertains more especially to that class of such devices inwhich thereis provided a roller and a series of cooperating devices, heretofore toothed wheels, between which the wick is engaged and raised and lowered.

The present invention has for its objects,

- among others, to provide an improved simple yet efficient form of device for this purpose by which the wick shall be raised and lowered absolutely evenly, so that an even flame shall be produced. In lieu of the toothed wheels heretofore proposed for this purpose and which engaged the wick and raised the latter only where the sharp points engaged in the same, and consequently caused an uneven flame, and therefore caused the stove to smoke, I employ a plurality of burs disposed on a shaft parallel with the shaft carrying the long roller, the burs and their shaft beingmounted in one portion of the casing and the roller and its shaft mounted in the other portion, the two portions being constructed and arranged to be detachably united, so as to permit access to the inclosed parts when necessary.

Still a further object is to so construct and join the burs as to permit of their ready removal when desired and permitting of the building up of a shaft of any desired length by merely increasing the number of the burs.

The burs are formed with hubs having interengaging hub extensions, and these are slidably and loosely mounted upon a common shaft, one of the burs being detachably fastened to such shaft and the others made to turn therewith by reason of their engagement .one with another and with the bur made fast to the shaft.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is a side elevation showing a portion of a burner provided with my present improvements. Fig. 2 is a horizontal section through the same on the line 2 2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a cross-section on the line 3 3 of Fig. 2 looking in the direction of the arrows. Fig. 4 is an elevation of a modified form of bur. Fig. 5 is an end elevation of Fig. 4. Fig. 6 is a front elevation of the device with the forward or inner part of the casing raised to uncover the series of burs and other parts. Fig. 7 is an elevation of the parts of the device seen in a direction opposite to that in which Fig. 6 is seen, parts being broken away and others in section.

Like numerals of reference indicate like parts throughout the several views in which they appear.

Referring now to the details of the drawings, 1 designates one portion of the casing formed of sheet metal, formed witha longitudinal bulge 2, forming a recess 3, within which is disposed a roller 4, the extensions or pintles 5 of which are mounted to turn freely within suitable bearings 6, formed by portions of the metal of the casing, portion 1 being pressed or otherwise treated to form the same, which prevents the endwise displacement of the rol]er, while yet allowing it to revolve freely. The other portion, 7, of the casing has a bulge 8, forminga space or chamber 9, within which theburs and their shaft are disposed, it being understood that the shaft of the burs is arranged parallel with the shaft of the roller, as seen clearly in Figs. 2 and 3.

The burs are of novel form and are all sleeved upon a shaft 10 common to them all. This shaft 10 has a bearing at one end in a bearing 11, formed by the bending of the metal of the portion 7, as seen clearly in Fig. 2, the other end being extended outside the casing, where it is provided with a suitable ICO knob or handle or wheel 12 or other analogous means whereby it may be revolved when desired. On this shaft are a plurality of burs 13, in this instance shown as five in number, although it is evident that this number may be increased or diminished, as may be found desirable. The burs each have their protuberances disposed in lines diagonally arranged, as seen clearly in Figs. 2 and 41, so as to provide a firm grasp upon the wick without the danger of raising the wick only at certain points, as is the case where a wheel with sharp points is employed. I

Each bur comprises a body portion having a longitudinal opening 14130 receive the shaft and ahub 15 with an extension formed at opposite ends with male and female portions 16 and 17 arranged to interlock. These male and female portions are disposed at right angles to each other, as seen best in Fig. 2, and the left-hand bur (seen in Fig. 2) is the only one secured to its shaft. afiixed detachably in any suitable manner, as by a brass sweat-pin l8, and the other burs are held to place by the interlocking of their male and female portions, as will be clearly understood from Fig. 2. The right-hand bur has its body portion engaged against a shoulder 19- on the shaft and an inward extension of the portion 7 of the casing, as shown in Fig. 6. By this means the burs may be quickly slipped on the reduced portion 10 of the shaft, the first against the said shoulders, and thus avoiding the careful placing of the bur in position to receive the pin which must pass into or through theshaft. Such pin must be riveted, which consumes further time. By the present construction all the burs can be quickly and easily slipped on the shaft and all secured by the single pin 18.

By removing the sweat-pin 18 all the burs may be removed from the shaft, they simply sliding easily onto the shaft, and may readily revolve thereon until the sweat-pin is put in place. This single sweat-pin holds all the burs against turning upon the shaft, as well as against longitudinal movements thereon.

Other forms of interlocking portions on the This may be burs may be employed other than that shown in Fig. 2. For instance, as seen in Figs. 4: and 5, the burs may have their hub extensions formed at their ends with radial teeth 20, which will interlock when the burs are disposed end to end upon their shaft, the result being the same as with that form of construction seen in Fig. 2.

The casing portions 1 and 7 have the vertical extensions 21and 22 to form the wicktube extended above and below the housing for the roller and burs, as seen clearly in Fig. 3.

The two portions of the casing are designed to be slidingly engaged the one with the other, as seen clearly in Fig. 2, each being provided at opposite edges with substantially semicircular flanges 23 and 24, which frictionally contact, so as to hold the parts against accidental disengagement.

What is claimed as new is In a wick-raising device. the combination with a two-part casing having oppositely-disposed bulges and one of said parts formed with integral shaft-bearings. and a tubular portion extending within the casing at one end, of a wick-raising shaft having at one end a shoulder, said shoulder and the inner end of said extension being in the same transverse plane to prevent endwise motion of the said shaft and its burs, said shaft being passed through the said extension, ahand-wheel upon the outer end of said shaft, and a plurality of burs loosely sleeved on said shaft and having interlocking portions at their ends, the bur at one end engaging the shoulder on the shaft and the inner end of the said extension, and a removable pin through the interlocking portion of the bur at the opposite end of said shaft and engaging the shaft, all sub stantially as and for the purpose specified.

1n witness whereof I have hereunto set my hand,this 12th day of April, 1904:, in the pres ence of two subscribing witnesses.

JOHN M. STOKOE.
